NTP8918
Power Driver Integrated Full Digital Audio Amplifier
General Description
The NTP8918 is a single chip full digital audio
amplifier including power stage for stereo
amplifier system. The NTP8918 is integrated
with versatile digital audio signal processing
functions, high-performance, high-fidelity fully
digital PWM modulator and two high-power
full-bridge MOSFET power stages.
The NTP8918 receives digital serial audio
data with sampling frequencies of 32kHz,
44.1kHz, 48kHz, and 96kHz. It delivers 2 x 15
watts in stereo mode without heat sink.
The NTP8918 has a mixer and Bi-Quad filters
which can be used to implement the essential
audio signal processing functions such as
loudness control, compensation of a loud
speaker response and parametric
equalization.
All the functions of the NTP8918 can be
controlled by internal register values via I2C
host interface bus.
